Struct DeltaDisplayFormatter 

pub struct DeltaDisplayFormatter { /* private fields */ }

Delta display formatter

Formats delta content for user display with consistent styling across all parsers.

Implementations

impl DeltaDisplayFormatter

pub const fn new() -> Self

Create a new formatter with default settings

pub fn format_thinking( &self, content: &str, prefix: &str, colors: Colors, ) -> String

Format thinking content specifically

Thinking content has special formatting to distinguish it from regular text.

pub fn format_tool_input( &self, content: &str, prefix: &str, colors: Colors, ) -> String

Format tool input specifically

Tool input is shown with appropriate styling.

Current Behavior

Every call renders the full [prefix] └─ content pattern. This provides clarity about which agent’s tool is being invoked.

Future Enhancement

For streaming tool inputs with multiple deltas, consider suppressing the [prefix] on continuation lines to reduce visual noise:

• First tool input line: [prefix] Tool: name
• Continuation: └─ more input (aligned, no prefix)

This would require tracking whether the prefix has been displayed for the current tool block, likely via the streaming session state.
